IPC: D02G1/16
Filed: 1957-05-31
Abstract: 871,799. Finishing yarns. BRITISH CELANESE Ltd. May 30, 1958 [May 31, 1957], No. 17376/57. Addition to 871,798. Drawings to Specification. Class 120(3) Yarn comprising bulky portions disposed at intervals along its length is produced by feeding a continuous filament yarn e.g. of cellulose derivatives such as cellulose acetate, polyhexamethylene adipamide, polyaminocaproic acid or polyethylene terephthalate, through a jet as described in the parent Specification, the pressure at which gas e.g. air or moist steam, is supplied to the jet being such as to maintain continuous supply of the initial yarn but cause intermittent bulking. A single yarn (or intertwisted ends which may differ in colour and lustre) of high or low twist (more than 2À5 or less than one turn per inch) may be fed to the jet via an inlet orifice of dimension sufficient only to permit free passage of the yarn; on emerging from the jet, the bulked yarn may impinge against a baffle plate and/or additional twist may be imparted. The Provisional Specification describes collection and subsequent withdrawal of the bulked yarn in and from a continuously rotating centrifugal pot e.g. as described in Specification 17,377/57. The yarn product may comprise the whole or part of the warp or weft or both in a woven fabric. Specifications 776,410 and 793,044 also are referred to.

Title: Device for positioning halftone negatives on transparent sheets
IPC: G03F9/00
Filed: 1974-04-19
Abstract: 1463872 Positioning negatives for preparing colour separation printing plates Y INOUE 19 April 1974 [26 April 1973] 17377/74 Heading G2A  A device for positioning half tone negatives A on a transparent sheet D, for preparing colour separation printing plates, comprises a negative positioning implement 32 having a bar 45, provided with pins 46 which engage holes in the negative, the bar being mounted for movement transversely, longitudinally and rotationally relative to a work table 11; when the negative, e.g. for yellow colour, has been moved to the desired position, it is detached from mounting pins 46 and secured to the sheet D e.g. with sticky tape; the transverse, longitudinal and rotational position of the bar 45 is memorized electronically, and memory return circuits enable the bar 45 to be returned to exactly the same position for positioning a second negative, e.g. for magenta colour, corresponding to the first negative for yellow colour, on a second sheet D. In the embodiment shown a frame 18 is moved longitudinally of the work table 11 by a threaded shaft 20 engaging a shift nut 23 and driven by a pulse motor 21. A member 30, which carries the negative positioning implement 32, is mounted on the frame 18 and is moved transversely by a threaded shaft 35 engaging a shift nut 37 and driven by a pulse motor 36. The implement 32 comprises a pivot 41 which carries bar 45 and which is rotated by gears 42 driven by pulse motor 43. A position detector is associated with each of the drive mechanisms and comprises a magnetic scale 25, 38 and 48 respectively, having alternate N and S poles, and location sensors 26, 39 and 49 respectively comprising a magnetic flux responsive to the magnetic scale. In operation a sheet D is placed on the work table and a negative for yellow colour mounted on bar 45. The drive mechanisms are actuated by a single hand lever 53 until the negative is in the desired position where it is detached from the bar and mounted on sheet D. At the same time a switch in a switch group (61) is actuated which causes the value of location sensors 26, 39 and 49 to be fed via detectors (55), counters (56) and memory return switches (57) to memory circuits (58). The address of the negative [yellow] is thereby memorized. Subsequently several negatives [yellow] are mounted in various positions on the same sheet D, the address of each negative being memorized by operating a different switch in the switch group (61). Sheet D is then removed from the work table and a second sheet placed thereon. Negatives for magenta colour, corresponding to the previously positioned negatives [yellow], are then mounted on the sheet, each negative being positioned by operating switches (57) which connect the memory circuit output to the pulse drive motors, and operating the relevant address switch of the switch group (61). The motors move the bar 41 to the correct position automatically. This process is repeated for negatives corresponding to all the required colours.

Abstract: 1356593 Feeding and delivering sheets EASTMAN KODAK CO 27 May 1971 [2 June 1970] 17629/71 Heading B8R Sheets stacked on edge in two hoppers 26, 28, Figs. 3 and 5, are fed in one mode of operation from one of the hoppers to a transfer chamber 40 and thence into the other hopper, or in another mode of operation from one hopper to the chamber 40, thence to a projection station 156 of a microfilm reader for observation by the operator, back to the chamber 40 and thence into the other hopper. Pile supports.-The hopper 28 (or 26) has an end plate 44 (or 46) which, when sheets are removed from the hopper, is urged against the back of the pile by a spring. Sheet separators.-The end sheet 36 is separated from the pile in the hopper 28 by a friction feed wheel 50 driven by a motor 68 and passed to feed rollers 58, while rollers 60 engage any second sheet 35 separated with the sheet 36 to urge it back into the hopper. The wheel 50 and rollers 58 are reversible according to the direction of movement of the motor 68 and according to which hopper the sheets are to be removed from. The rollers 60 and corresponding rollers 62 for the hopper 26 always rotate in the same direction. Sheet forwarders.-A separated sheet is advanced by the rollers 58 and idler rollers 64, 66 into the chamber 40 and up to the nip of rollers 150, 152. In the first mode of operation, the rollers 150, 152 rotate so as to reject the sheet, which becomes bowed so that the trailing edge is moved by the rollers 58 along the surface of the latter and into engagement with the opposite idler rollers 66 (or 64). In the second mode, the rollers 150, 152 advance the sheet to the station 156. Delivering sheets.-A sheet in the station 156 after reading is returned by the reversible rollers 150, 152 to the chamber 40, and thereafter such a sheet, or a sheet which has not been admitted to the station 156 and has been bowed while in the chamber 40, is delivered by the rollers 58 and 66 (or 64) to the opposite hopper from that from which it came. Receptacles.-The motor 68 rotates a cam which causes card-deflecting arms 52, a card return wheel 56, and a card deflector 54, to be swung against the plate 46 (or 44) or any sheets already stacked thereagainst, of the receiving hopper 26 (or 28), so as to force the pile and plate backwards. The arms 52 deflect a delivered sheet against the pile or plate, and the wheel 56, which is also rotated by the motor, completes the delivery of the sheet against a back wall 27, a finger 119 on an arm 118 carrying the wheel 56 preventing the sheet being carried round the wheel 56. Controlling.-Electric switches actuated by the passage of sheets prevent feeding of sheets from a hopper into the chamber 40 when there is already a sheet in the chamber or in the station 156. Sheet reader.-Means for positioning a sheet in the station 156 is described in Specification 1,356,594.

Filed: 1954-06-21
Abstract: 752,278. Dynamo-electric machines. PESTARINI, J. M. June 21, 1954, No. 18179/54. Drawings to Specification. Class 35. [Also in Group XXXVII] Relates to a system in which a dynamoelectric machine, acting as a receiver, is driven in synchronism with another machine which operates as a transmitter, both machines having primary windings each of which may be mounted on a rotor and connected to a singlephase source of constant voltage and frequency, and secondary stator windings which are interconnected by means of three-phase lines. A capacitor of suitable value is connected in parallel with the primary windings in order to increase the torque that the receiver is capable of exerting before it falls out of step. The primary windings of the machines may be mounted on rotors formed of laminated iron, or the primary windings may be rotatable in air gaps between stationary core members in order to reduce inertia. The stationary core members of each machine on each side of the air gap may carry polyphase secondary windings, these two windings being interconnected. In another arrangement, the primary winding of the transmitter is in the form of a closed armature winding associated with a commutator bearing rotatable brushes which convey the single-phase supply current to the primary winding. The laminated iron core which carries the primary windings of the receiver may be stationary or rotatable by means of an auxiliary motor. In a further embodiment, the transmitter has a fixed secondary polyphase winding embedded in a laminated iron stator, and a rotatable primary winding which forms a closed loop and co-operates with a commutator. The primary winding rotates in an airgap between the stator and an internal iron core and is driven by an auxiliary motor at a speed approaching the speed of moving brushes which co-operate with the commutator. A number of receivers may be controlled by a single transmitter.
